SPECIFICATION forming part of Letters Patent No. 605,242, dated June 7,1898. Application filed October 18, 1397. "Serial No. 655,618. (Nomodel.)

To aZZ whom, it may concern.-

Be it known that I, ANTONIO ALITTO, a citizen of the United States,residing at Chicago,

in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Steve or other Grates, of which the followingis a specification.

My invention has for its primary object to so construct a sectionalgrate that by rocking the sections grate-surfaces at higher or lowerlevels may be presented; further, to provide for the clearing of asectional rocking grate; also, to control the rocking of thegrate-sections upon their pivots, and, finally, to improve theconstruction of the clearing-rake to render its operation moreconvenient and lessen the liability to cramping and binding; and itconsists in combining in a grate'two rocking sections, each of which hasa horizontal series and a vertical series of gratebars rocking upon thelongitudinal axis of the horizontal series, the vertical series normally forming the sides of a basket-like grate and being swung up andbrought together when the sections are rocked to afford an elevatedgrate; in combining with a sectional grate the sections of which rockupon independent axes a rakemovable longitudinally of the grate-bars anda guard-recess at the rear, beyond the ends of the grate-sections, intowhich the rake head and teeth enter at the extreme of their inwardmovement, out of the Way of the grate-sections when they rock; incombining with such rocking sections and recessed end bar a rake-headmovable upon ways longitudinally of the grate-bars, and lateraldraw-rods extending from the ends of the rake-head alongside butexterior to the grate to the outside of the stove and there united by across-bar, whereby the space beneath the grate is left clear and alldanger of twisting or binding the rake is obviated, and in the variousother combinations and details of construction hereinafter described andclaimed.

In the drawings, Figure 1 is a top plan view of a firebox and grateembodying my invention. Fig. 2 is a vertical longitudinal sectiontherethrough on the correspondinglynumbered line in the precedingfigure. Fig. 3 is a vertical transverse section on the line 3 3 of Fig.1, showing the elevated position of the grate in dotted lines; and Fig.i is a detail of the mechanism for rocking or dumping the grates.

Ais a fire-box, in which are mounted the rocking grate-section's B,which, so far as relates to the first feature of my invention, are twoin number and are constructed with a normally horizontal row of bars I)and a vertical row I), rigid with the horizontal row, giving incross-section the form of a letter T, with the stem horizontal, theupper bars of the vertical rows normally constituting the side walls ofthe grate. The horizontal row of each section rocks upon the axis of itscentral bar for dumping or discharging the oontents of the grate, and ifthis rocking move ment is continued sufficiently the side rows orvertical rows will be carried up overhead until they meet in theposition indicated in dotted lines in Fig. 3, striking the stop b andform an elevated grate-surface, thus permitting a small fire to be builtclose to the top of the stove for hasty work or to suit the temperatureof the season. To insure this action of the grate-sections in forminglower and upper grate-surfaces at will it is necessary that they shouldrock simultaneously and in opposite directions. Convenient means forthus controlling them are provided by carrying the front trunnions ofthe pivotal centralbars to the exterior of the fire-box and there keyingto them two intermeshing equal segment-gears O 0, one of which carries asecond segment-gear D, which meshes into the rack d of a slide-bar D,supported in suitable guides d to extend horizontally across the frontof the fire-box. The end of this rack-bar is or may be flush with thefirebox when in its normal position, to permitthe box to be removed fromthe stove, and in such relation the lower grate-surface is in effectiveposition; but it is extended through the side E of the stove or range bymeans of a knob and shank E, the shank part of which screws into the endof the rack-bar, as shown in Fig. 4, and by means of this knob it can bedrawn out to dump the contents of the lower grate or to bring intoeffective position the sections of the upper grate or pushed in to dumpthe upper grate or close the lower grate.

To prevent coal from falling between the vertical rows of grate-bars andthe side walls of the fire-box when the lower grate is in use,shield-ledges e are arranged along said walls immediately above thespaces thus formed and extending into close proximity with the upper barof each vertical row.

The upper grate, being intended for quick fires of a temporarycharacter, does not need any special clearing arrangement; but for thelower grate I have provided the cleaning-rake F, having upright teeth f,rigid with the rakehead, passing up a short distance between thegrate-bars. This rake moves upon the ways F, arranged along the sides ofthe fire-box, and is operated by means of the parallel rods G, whichextend above said bars outside the path of the grate-sections in theirrocking movement and pass through apertures in the front of the fire-boxand of the stove or range and are connected outside of the latter by across-bar G,carryiug a handle H, whereby therake can be pushed to andfro. This arrangement leaves a clear space beneath the grate and insuresagainst the twisting, cramping, or binding of the rake-head, since bothends will be drawn upon equally whatever the obstruction.

In order that the rake may not interfere with the rocking of thegrate-sections, the rear trunnions of the pivotal grate-bars are jour-.naled in hangers 7c from a journal-plate K,

set out from the rear wall of the fire-box by means of a horizontalspacing-bar K, thus forming a guard-recess into which the rake may enterat the extreme of its rearward stroke and not only be out of the way ofthe sections when they rock, but be completely sheltered against chokingby the lodging of coal or cinders. Access to this recess is gained bymounting the rear ends of the gratebars in frame-plates L, which arepierced, as

1." The combination with grate-sections arranged side by side, bearingslocated in line with the central longitudinal ends of each section, uponwhich they rock, and means for rocking said sections simultaneously, ofa clearing-rake reciprocable on ways beneath,

said sections and having teeth extending up between the longitudinalgrate-bars, and means whereby said rake is allowed to pass beyond oneend of said sections, to permit them to be rocked.

2. The combination with grate-sections arranged side by side, aninclosing fire-box, a journal-plate set out from the rear wall of saidfire-box to form a guard-recess, pierced frame-plates for the rear endsof the gratebars, bearings in the journal-plates and in the front wallof the fire-box in line with the central longitudinal axis of eachgrate-section for the support of such section, means for rocking thesections simultaneously, and a reciprocable clearing-rake arranged topass said pierced support and into the guard-recess.

In testimony whereof I aflix my signature in presence of two witnesses.

ANTONIO ALITTO.
